KNOB FOR STOVE-DOORS.

Application filed February 4. 181-2.

To all whom it may concern.-

Be it known that I, HENRY A. TWEED, of the city of Brooklyn and State ofNew York, have invented a new and useful Improvement in Knobs forStove-Doors, of which the following is a full, true, and exactdescription, reference being bad to the accompanying drawlugs.

My invention is especially applicable to that class of knobs which aremade of stamped metal and when completed are hollow. In knobs of thisclass the attaching-screw is held to the knob by means of a screw-threadcutin a body of metal, which is in some way attached to the knob. Theseknobs are generally circular in form, and it is consequently importantto prevent the revolution of such metal within the knob.

My invention will be readily understood from the accompanying drawings,in which Figure 1 represents a vertical section, and Fig. 2 anindependent detailed view.

A and B represent the two parts of a knob. C, Fig. 2, is a circularplate of metal having a. screw-thread cut through it, with which threadthe screw D is adapted to engage.

In process of formation the metal plate 0 is first dropped into thebottom of the cylinder, which is afterward to be shaped to the con- (Nomodel.)

figuration shown at B, and is then so struck with a die as to force upthe metal of the lower part or bottom of the cylinder into theindentations or grooves E, which have been previously formed by a die.The part B being spun in over 0 said plate is prevented from movingvertically by the inwardly-projecting portion of said part B, and isprevented from revolving by the metal of the part B entering within thegrooves or indentations E. In this way a cheap and sure method isprovided of 0 HENRY A. TWEED.
